| Abstract: | The reason of low efficiency of total nitrogen (TN) removal in the first phase of Pingdingshan Sewage Treatment Plant is analyzed. The effective measures are taken to tackle this problem,including adjusting the feed water quality,improving the biodegradability of sewage,changing the Carrousel oxidation ditch into a modified oxidation ditch,etc. Results show that TN in the effluent can meet the Class A of "Discharge Standard of Pollutants of Municipal Wastewater Treatment Plant" (GB18918-2002). |
